Watch the One Direction nominate Kanye and co. in his sexy, husky voice and get a big blue bucket of frigid H2O dumped on his head from a balcony.

Harry isn't the first 1D member to take the challenge; Liam Payne enlisted a group of girls to pour water on his head on Thursday, and Louis Tomlinson jumped into a lake on Friday (August 22). Niall, who went all wet-T-shirt with his challenge, nominated Louis. We're just waiting on you, Zayn... let the hashtags begin. #ZAYNDOTHEICEBUCKETCHALLENGE
